A window definition used to perform calculations within the PivotDashboardItem.

ImplementsA window definition is used to apply calculations to measure values. To specify a window, create and initialize the PivotWindowDefinition class and assign the resulting object to the Measure.WindowDefinition property.
The PivotWindowDefinition class allows you to specify the window for the Pivot dashboard item.
The assignment of a PivotWindowDefinition instance to the MeasureDefinition.WindowDefinition property is required to perform window calculations.
The code snippet adds a new measure to the Pivot dashboard item and specifies a window calculation to compute the difference between measure values across a window. The calculation is performed along columns of the Pivot dashboard item.
using DevExpress.DashboardCommon;
using DevExpress.DashboardWin;
// ...
PivotDashboardItem pivotItem = dashboardViewer1.Dashboard.Items[pivotItemName] as PivotDashboardItem;
if (pivotItem != null)
{
Measure extendedPrice = new Measure("Extended Price")
{
Name = "Diff",
ShowGrandTotals = false
};
PivotWindowDefinition pivotWindowDefinition = new PivotWindowDefinition();
pivotWindowDefinition.DefinitionMode = PivotWindowDefinitionMode.Columns;
extendedPrice.WindowDefinition = pivotWindowDefinition;
extendedPrice.Calculation = new DifferenceCalculation() { DifferenceType = DifferenceType.Absolute };
pivotItem.Values.Add(extendedPrice);
}
